Application filed March 17, 1913.

To all whom it may concerti.'

Be it known that GEORGE A. VEHNER, a citizen of the United States, and aresident of Savannah, in the county of Chatham and State of Georgia,have invented a new and useful lmprovenient in PermutationLocks, ofwhich the following is a speciication.

My invention is an improvement in permutation locks, and has for itsobject the provision oi a lock of the character speciiied, designed toruse with automobiles, and arranged to alternately connect a source ofelectrical energy with the motor to start the saine and with themagneto, wherein the lock is normally prevented from movement byreleasable mechanism, operated by a selection from a plurality of pushpins of a series, wherein the selection ot push pins .may be varied toprovide for changes in the combination, and wherein the changingmechanism is normally locked in an inactive position and may be releasedonly by operatand on its outer tace ywith a circular recess ing theproper selection of push pins.

ln the drawings: Figure 1 is a perspective view ot the improved lock,Fig. 2 is an enlarged vertical section, Fig. 3 is a rear view of theoperating mechanism, Fig. 1- is a transverse vertical section of theoperating dial or knob, showing the parts in one position, Fig. 5 is asimilar view showing the parts in another position, Fig. 6 is aperspective view ot one of the push pins, Fig. 7 is a similar view ofanother'of the said pins, and Fig. 8 is a side view of the actuatingsleeve of the lock.

The present embodiment of the invention is shown connected with a plate1, which forms a closure for a receptacle or recess in that portion ofthe hood 2 of an automobile which is directly in front of the driver,and the opening of the recess is inclosed by a Jframe 3, secured to thehood, the plate 1 closing the opening of the saidframe and concealingthe recess from view.

The trame 3 is secured to the plate 2 ot the hood by means of screws -1or the like, and it will be noticed that the plate 1 is provided at itsupper end with an inwardly Specification of Letters Patent.

,the ring or collar.v

A pin or rod 22 is arranged in the hub or bushing 17, the said rodhaving a head 23 Patented July 111, 1914.

the lower end thereof, and a' screw 10 is passed through the slot andthreaded into the bolt 7, for operating the said bolt, the head ot' thescrew being on the outer tace of the plate. Vlhen the bolt or latch 7 ismoved upwardly in the bearing 8 by means of the screw 10, the lower endof the bolt releases its engagement with the trame 3, and the plate andits attachments may be removed from the opening in the plate 2 of thehood.

The bolt is provided with an inwardly offset upwardly extending lug 11,for a purpose to be described, and for the additional purpose oflimiting the downward movelment of the bolt. That portion of the boltwhich engages the frame 3 is outwardly offset to form a shoulder 12,between the said portion and the body of the bolt, and the said shoulder12 engages a similar shoulder A13 on the plate to limit the upward move#ment of the bolt.

The plate 1 is provided near its upper end 111, and with an opening 15at the center of ythe said recess. The operating sleeve 16 is 4.providedwith a cylindrical hub or bushing at its outer end, and the inner end ofthe rod is conical as indicated at 24. The rod is vmovablelongitudinally of the hub, and a 27 Vwhich tits outside of the saidsleeve 16,

the body of the knob fitting within the sleeve and illing the same. Theknob is also provided with an annular radial flange 28, which extendsbeyond the sleeve 27, and the outer tace of the said sleeve 27 isprovided 'with a plurality of recesses29,`each of which has its sideedges undercut as indicated at 30, and plates 31 are fitted in therecess, the said plates having their side edges beveled to engage theundercut walls 30 of the recess.

It will be noted from an inspection of Figs. 2, 4 and 5, that the bodyof the knob 26 is provided with two series yof radial openings 32, themembers of each series being spaced at angular distances of 90o withrespect to each other and the members of one series alternating with themembers of the other series. A coil spring 33 is seated in each of thesaid openings, and a push pin engages the outer end of each spring. Theoperating sleeve 16 is provided with two annular series ofcircumferentially extending slots 34, each slot having a circularenlargement 34a at its center.

The push pins, before mentioned, are mov able in the slots 34, and thesleeve 27 of the knob is provided with openings registering with theslots 34 and with the openings 32 of the body of the knob. The curvedplates 31 are provided with slots 35, the said slots extending to theouter edges of the plates for receiving the pins before mentioned.

The push pins are divided into two series, one series being arrangednearer the plate than the other. The pins are shown in Figs. 6 and 7 andeach series consists of four pins, two as shown in Fig. 6 and two asshown in Fig. 7. Each of the pins shown in Fig. 6 comprises a head 36, acylindrical inner end 37, a portion 38 substantially rectangular incross section adjacenty to the head, a portion 39 substantiallyrectangular in crossl section adjacent to the inner end and a connection40 between the v 41, which is the operating pin for the'mechanism to beoperated. The said pin moves in an arc-shaped slot 42, in the plate 1,before mentioned. The sleeve 16 is prevented `from rotation on the plateby means of screws 43, which are passed through from .the rear face ofthe plate and engage the said sleeve to hold the same rigid with respectto the plate. On this account it will be evident that to permit therotation of the knob to operate the pin 41, the push pins must be insuch position that a iiattened orv substantially rectangular portion of.each pin will engage the slot 34 through which the pin` passes. All ofthe said pins are normally held in outward position by the springs andin the normal condition of the knob, any or all of the vsaid pins may bepressed inward without resistance. Certain ofthe pins however must bepressed inward to permit the rotation of the knob, and the other pinsare so arranged that should any except the selected pins be pressedinward,

the knob cannot rotate. In other words, the selected pins and only theselected pins must be pressed inward to permit the knob to properlyoperate.

The pins are numbered o-n the face of the knob or dial as indicated inFig. 1, the numbers running from l to 8 clockwise. It will benoted froman'inspection of Fig. 4 that two pins, namely 1 and 3, are out ofregisterv with the sleeve 16, that is, the said pins have theircylindrical portions 37 in the .portions 34L of the respective slots 34of pressed inwardly will. prevent the rotation of the knob, and a4positive series which must be pressed inbefore the knob can be rotated,and which in normal position will prevent the rotation of the knob. Thefirstnamed series are shown in Fig. 7 and the last-named in Fig. 6.

To change the combination ofthe knob or dial, the knob must be turned tothe rightv or the left, after'the proper selection of pins have beenoperated to move the pin 41 from its position directly abovethe lug 11of the bolt. stands directly above this lug, and prevent-s themovementfof the bolt. After the knob has been turned torelease the bolt,vthe bolt is pressed upwardly and the lower edge of the plate 1 isdisengaged from` the opening lof the hood. The lifting outyof the lowerend releases the upper end. The dial or knob is then removed from theplate by removing the setscrew 21 withdrawing the screws'43 and afterthe knob has been re-y moved, the plates 31 may be slipped out -wardlyaway from the flange 28' to permit the removal and replacement of thepushv pins. In this manner any desired combination or selection may beprovided for and the combination may be changed as often as necessary.

lt will be noticed from an inspection of Fig. 3 that a pair of levers7() and 70a is pivoted on the hub or bushing 17 of the operating sleeve.Each lever is provided at its upper end. with a lateral lug 71 and aycoil spring 72 is arranged between the-lugs. The lower end of the leverremote from the plate 1 is oiiset inwardly toward the plate7 asindicated at 73, to cause the llower ends of. the levers to lie inapproximately vthe same plane, and the said lower ends of the leversengage on opposite sides of the pin 41.

The plate l is provided with'a stop 11a, and the said lower ends of thelevers 7 Ol and 7 0n engage opposite sides of the stop.

It will be evident thatI when the pin l1 is moved in either direction,that lever toward whose lower end the pin is moved, will be swung awayfrom the other lever, thus placing the spring 72 under tension. As forinstance, when the pin is swung toward the lower end of the lever havingthe oliset portion 73, the said lever will be swung as indicated indotted lines in Fig. 3, and as soon as pressure on the lever isreleased, the spring 7 2 will tend to return the lever to its originalposition, thus moving the pin Zil to normal position. The lever fromwhich the pin moves is prevented from movement by the stop lla.

The operation of the lock is as follows: To permit the knob to turn, thepush pins of the active series are pressed inwardly against theresistance of the springs, until the heads thereof engage the outersurfaces of the plates 3l. This movement of the pins moves thecylindrical portion of the said pins inwardly so that the saidcylindrical portions no longer register' with the openings Saa of thesleeve 16, but instead a flat-tened portion, and the knob is ready toturn, the flattened portion of the push pins moving in the rslots Sil.The knob may be moved in either direction, and when restored to itsoriginal position and the pins are released, they are moved outward,thus again locking the knob to the sleeve. Should for inst-ance thecombination be 1, l and 7, the pins 1, 4 and 7 are depressed. Should anyof the pins of the passive series be depressed the knob will be heldfrom angular movement, even though the correct pins of the active serieswere in proper position, since the pins of the passive series normallystand with a tlattened portion registering with the slots 34.
